• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yang) OR (dong yang)) hua gene tang jie ((chong ghi) OR (zhong zhi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) or (dong yang)) hua gene tang jie ((chong ghi) OR (zhong zhi)) ;*".
